JACOB DAvID, or BROOKLYN, NEW YORK, "ASSIGNOR or ONE-HALF TO EDWARD A. DDVEAI OF SAME PLACE.

I WANTAGE OR ULLAGE ROD.

SPECIFICATION forming part of Letters Patent No. 280,586, dated July 3, 1883.

Application filed November 16, 1882. (No model.)

To all whom it may concern:

Be it known that I, JACOB DAVID, a citizen of the United States, residing at Brooklyn, in the "county of Kings and State of New York, have invented a new and useful Wantage or Ullage Rod, of which the following is a specification.

My invention relates to improvements in rods having a number of scales and figures marked thereon to gage and ascertain the ullage of different-sized barrels which contain liquid. The rods at present in use have a stationary or fixed lip at zero, which lip has to be placed against the under or interior side ofthe bung-hole stave when inserted into the barrel through the bung-hole.

The object of my invention is to expedite finding the wantage of barrels containing liquid, and to find the wetline with great accuracy. I attain these objects by substituting a movable lip for the fixed lip at present in use 011 a wantage-rod, a description whereof is hereinafter more fully set forth, and the mechanism is illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of the top portion of a wantage-rod with my attachment. Fig. 2 is a cross-section of the rod. Fig. 3 is a cross-section of the rod and attachments on the line 00 y. Fig. 4 is an elevation of the attachment. Fig. 5 is a cross-section of the tube M and parts F O 011 the line a y.

Similar letters refer to similar parts throughout the several views.

A is the top portion of a square rod, such as are in common use by gagers, having a number of scales and figures on the several sides to mark the distance from the surface of the fluid in a barrel to the bung-stave and ascertain the wantage.

B is a lip that catches under and is held against the under side of the bung-stave when the rod is inserted into a barrel through the bung-hole. The zero-line on the rod is indicated by the dotted line at B. The dotted line marked B also shows where the permanent lip is placed on wantage-rods as at present used.

' K is a cylindrical longitudinal chamber that is made in the rod A, as shown by the vertical section, Fig. 1, and the cross-section plan views, Figs. 2 and 3, and having a slot the whole length of the chamber, from the longitudinal cylindrical chamber K to the outside of one side of the rod A, as shown at the crosssectional plan views, Figs. 2 and 3.

H is a plug that is fitted into the top of the cylindrical chamber A, into the under side of which plug is inserted a screw marked L.

The tube M is just of sufficient diameter to play up and down easily inside the longitudinal cylindrical chamber K, and inside the tube M is fitted a spiral spring, G, which spring, G is fastened one end to the bottom of the chamber K at P, and the other end is fastened to theinside of the tube M at Q. The tube M is connected to the handle 0 D and lip B by the.

flat piece F, as shown at Figs. 1, 3, 4, and 5, which piece F is just the same width as the depth of the slot made from the outside of the rod A into the chamber K, and not as thick as the width of the slot, as shown at Fig. 3.

To ascertain the distance from the fluid-line to the bung-stave in a barrel containing liquid, insert the rod A'through the bung-hole and catch the lip B under the bung-stave. Hold the lip firmly against and under the side of the bung-h ole by the handle 0 D. By pushing down on the rod A until the top of the inside tube, M, strikes against the set-screw L the lip B will be at the zeroline, as shown by the dotted line at B, Fig. 1, and the handle 0 D, attached to the lip, will be in the position occupied by the dotted line C D. Upon releasing the pressure on the rod A the spring G will draw the rod out of the fluid, when the rod may be removed from the barrel, showing on the rod the distance of the wet-line from the under side of the barrel-stave.

The set-screw L can be lengthened or shortened to maintain the lip B at the zero-linewhen the tube M'is brought in contact with it.

When a lip is fixed and stationary at the zero-line on a wantage-rod, great care must be taken when inserting the rod or the wet-line will show too high on the rod, if thelip is allowed to drop below the under side of the stave; but by having a movable lip on a wantage-rod, which is held in position some distance below the zero-line when inserted into a barrel, no great amount of exactness or care is required, as the true wet-line will not be found until the rod is pressed down into the therein, in combination with a movable lip IO fluid and the lip is brought to the zero-line. having a handle, 0 D, asliding tube, M, spring hat I claim as my invention is-- G, and connecting-piece F, subslmilviully as 1. In combination with 1L vantage-rod, a 1 shown and described. 5 movable lip held in position by a spring, substantially as shown and described.
